Personalis, Inc. Commitments Disclosure

Note 11. Commitments and Contingencies

Contingencies

The Company is subject to claims and assessments from time to time in the ordinary course of business, including claims from customers and vendors, pending and potential legal actions for damages, governmental investigations and other matters. For example, the Company has received, and may in the future continue to receive letters, claims or complaints from others alleging false advertising, intellectual property infringement, and/or violation of employment practices. Accruals for litigation and loss contingencies are reflected in the consolidated financial statements based on management’s assessment, including the advice of legal counsel, of the expected outcome of litigation or other dispute resolution proceedings and/or the expected resolution of contingencies. Liabilities for estimated losses are accrued if the potential losses from any claims or legal proceedings are considered probable and the amounts can be reasonably estimated. Significant judgment is required in both the determination of probability of loss and the determination as to whether the amount can be reasonably estimated. Accruals are based only on information available at the time of the assessment due to the

uncertain nature of such matters. As additional information becomes available, management reassesses potential liabilities related to pending claims and litigation and may revise its previous estimates, which could materially affect the Company’s consolidated results of operations in a given period. As of December 31, 2025, the Company was not involved in any material legal proceedings.

Indemnification

In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and provide for general indemnifications. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future, but that have not yet been made. To date, the Company has not paid any claims or been required to defend any action related to its indemnification obligations. However, the Company may record charges in the future as a result of these indemnification obligations.

In accordance with the Company's bylaws and/or pursuant to indemnification agreements entered into with directors, officers and certain employees, the Company has indemnification obligations to its directors, officers and employees for claims brought against these persons arising out of certain events or occurrences while they are serving in such a capacity. The Company maintains a director and officer liability insurance coverage to reduce its exposure to such obligations, and payments made under these agreements. To date, there have been no indemnification claims by these directors, officers and employees.
